a–e Map view of volumetric strain changes due to earthquakes. The dotted lines represent isograms of volumetric strain changes in each of the five earthquake scenarios (Fig. 3) at a depth of 20 km beneath Mt. Fuji. The unit is 1 μ strain. Positive values indicate dilation, and negative values indicate compression. The orange solid triangle, orange open triangle, red broken line, and blue squares have the same meanings as in Fig. 2
